We have wide distribution, and our games are played by millions of people every month by players all over the world.
We are now looking for a Senior Client Platform Developer to join our growing Stockholm team. In this role, you will take a leading technical responsibility for our client-facing platforms and tools, helping shape architecture, drive best practices, and ensure a high-quality experience for players and internal teams.
The Role
Your key responsibilities include:
Technical Ownership & Architecture
Own and evolve core client-side platform components, including in-game UI systems and client-communication layers.
Contribute to architectural decisions around scalability, maintainability, and long-term platform strategy.
Identify technical debt and proactively drive improvements and refactors.
Platform Integration & Cross-Team Collaboration
Lead and design client-side integrations between our games, external platforms, and third-party studios using our OpenRGS platform.
Act as a technical partner to backend teams, ensuring coherent end-to-end platform architecture.
Provide guidance and best practices for external studios integrating with our platform.
Tooling, Automation & Developer Experience
Design, build, and maintain internal tooling (e.g. mock clients, launchers, automation scripts, CI helpers) to improve developer productivity and reliability.
Advocate for better workflows and testing strategies.
Technical Leadership & Support
Serve as a go-to expert for complex platform-related issues, supporting developers, QA, and tech support.
Drive root-cause analysis of production issues and help define preventative measures.
Mentor less-experienced developers through code reviews, technical discussions, and knowledge sharing.
UX & Quality Focus
Ensure high-quality user experiences by balancing technical constraints with UX and visual polish.
Collaborate with designers and product stakeholders to ensure robust and user-friendly client solutions.
What We're Looking For:

Several years of professional experience developing complex web or client-side applications in production environments.
Proven ability to take ownership of systems and make sound technical decisions with long-term impact.
Strong Technical Foundation
Deep proficiency in JavaScript/TypeScript or similar languages.
Solid understanding of modern web technologies, including browser APIs, cross-origin communication (postMessage, CORS), WebSockets, and real-time client-server communication.
Problem Solving & Debugging
Advanced debugging skills using browser DevTools, network inspection, and API tools (Postman or equivalent).
Ability to reason about complex distributed systems and client-server interactions.
Communication & Collaboration
Comfortable explaining technical concepts and trade-offs to both technical and non-technical stakeholders.
Experience working cross-functionally and influencing decisions beyond your immediate team.
Ownership Mindset
Proactive, service-minded, and comfortable driving initiatives independently.
Willing to challenge existing solutions and suggest improvements when appropriate.
Nice to Have:
Experience with Haxe.
Experience with Git, TypeScript, React, Linux, Bash, npm, Bun, Docker, Cucumber, GitLab CI, and AWS.
Experience working with web-facing C# systems.
